                                     GENERAL

1.   General information. Furnish the following as to the applicant:

     (a)  Form of organization. Mueller Industries, Inc. (the "Company") is a
          corporation.

     (b)  State or other sovereign power under the laws of which organized. The
          Company is organized under the laws of the State of Delaware.

2.   Securities Act exemption applicable. State briefly the facts relied upon by
     the applicant as a basis for the claim that registration of the indenture
     securities under the Securities Act of 1933 is not required.

     On September 2, 2004, the Company announced that it had authorized a
dividend of (1) $6.50 in cash and (2) $8.50 in principal amount of the Company's
6% Subordinated Debentures due 2014 (the "Debentures"), per share of the
Company's common stock, par value $0.01 per share ("Common Stock"), payable to
the holders of record of the Common Stock at the close of business on a record
date to be determined, subject to the satisfaction of certain conditions and the
occurrence of certain events. The Debentures will be issued pursuant to an
Indenture to be dated as of [_______], 2004 (the "Indenture"), between the
Company and [____________], as trustee (the "Trustee").

     The Company believes that the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act"), do not apply to the
Company's distribution of the Debentures to its stockholders as a dividend since
there will be no "sale" of the Debentures. Section 2(3) of the Securities Act
provides that a sale "...shall include every contract of sale or disposition of
a security or interest in a security, for value." The Company will be
distributing the Debentures to its stockholders on a pro rata basis and no
consideration will be given by its stockholders in exchange for the receipt of a
Debenture.

                                  AFFILIATIONS

3.   Affiliates. Furnish a list or diagram of all affiliates of the applicant
     and indicate the respective percentages of voting securities or other bases
     of control.

     (a) Each of the directors and executive officers of the Company may be
deemed to be an affiliate of the Company by virtue of his or her position. The
following table sets forth, as of August 31, 2004, the number and percentage of
shares of Common Stock beneficially owned by each of the Company's directors and
executive officers (calculated based on 36,003,353 shares outstanding on August

     (b)  Give a brief outline of the voting rights of each class of voting
          securities referred to in paragraph (a) above.

     Common Stock. The holders of Common Stock are entitled to one vote per
share for each share held of record on all matters submitted to a vote of
stockholders, including the election of directors. There is no cumulative
voting.


                                       5




     Preferred Stock. The Board of Directors of the Company is authorized to
provide for the issuance of shares of Preferred Stock in one or more series,
with such voting powers, full or limited, as may be determined by the Board of
Directors; provided that the Company may not issue non-voting equity securities.

     Series A Junior Participating Preferred Stock. Each share of the Company's
Series A Junior Participating Preferred Stock entitles the holder thereof to
1,000 votes on all matters submitted to a vote of the stockholders of the
Company, as adjusted for stock splits, stock dividends, combinations and the
like. The holders of shares of Series A Junior Participating Preferred Stock and
the holders of shares of Common Stock vote together as one class on all matters
submitted to a vote of stockholders of the Company, except as set forth below or
as required by law.

     If at any time dividends on any Series A Junior Participating Preferred
Stock shall be in arrears in an amount equal to six quarterly dividends thereon,
the occurrence of such contingency shall mark the beginning of a period (a
"default period") which shall extend until such time when all accrued and unpaid
dividends for all previous quarterly dividend periods and for the current
quarterly dividend period on all shares of Series A Junior Participating
Preferred Stock then outstanding shall have been declared and paid or set apart
for payment. During each default period, all holders of Preferred Stock
(including holders of the Series A Junior Participating Preferred Stock) with
dividends in arrears in an amount equal to six quarterly dividends thereon,
voting as a class, irrespective of series, shall have the right to elect two
directors of the Company. During any default period, such voting right of the
holders of Series A Junior Participating Preferred Stock may be exercised
initially at a special meeting of stockholders, and thereafter at annual
meetings of stockholders, provided that neither such voting right nor the right
of the holders of any other series of Preferred Stock, if any, to increase, in
certain cases, the authorized number of directors shall be exercised unless the
holders of ten percent 10% in number of shares of Preferred Stock outstanding
shall be present in person or by proxy. The absence of a quorum of the holders
of Common Stock shall not affect the exercise by the holders of Preferred Stock
of such voting right. At any meeting at which the holders of Preferred Stock
shall exercise such voting right initially during an existing default period,
they shall have the right, voting as a class, to elect directors to fill such
vacancies, if any, in the Board of Directors as may then exist up to two
directors or, if such right is exercised at an annual meeting, to elect two
directors. If the number which may be so elected at any special meeting does not
amount to the required number, the holders of the Preferred Stock shall have the
right to make such increase in the number of directors as shall be necessary to
permit the election by them of the required number. After the holders of the
Preferred Stock shall have exercised their right to elect directors in any
default period and during the continuance of such period, the number of
directors shall not be increased or decreased except by vote of the holders of
Preferred Stock or pursuant to the rights of any equity securities ranking
senior to or pari passu with the Series A Junior Participating Preferred Stock.

     Unless the holders of Preferred Stock shall, during an existing default
period, have previously exercised their right to elect directors, the Board of
Directors may order, or any stockholder or stockholders owning in the aggregate
not less than ten percent of the total number of shares of Preferred Stock
outstanding, irrespective of series, may request, the calling of a special
meeting of the holders of Preferred Stock, which meeting shall thereupon be
called by the


                                       6




President, a Vice-President or the Secretary of the Company. Notice of such
meeting and of any annual meeting at which holders of Preferred Stock are
entitled to vote shall be given to each holder of record of Preferred Stock by
mailing a copy of such notice to him at his last address as the same appears on
the books of the Company. Such meeting is required to be called for a time not
earlier than twenty days and not later than sixty days after such order or
request or in default of the calling of such meeting within sixty days after
such order or request, such meeting may be called on similar notice by any
stockholder or stockholders owning in the aggregate not less than ten percent of
the total number of shares of Preferred Stock outstanding. No such special
meeting shall be called during the period within sixty days immediately
preceding the date fixed for the next annual meeting of the stockholders.

     In any default period, the holders of Common Stock, and other classes of
stock of the Company if applicable, shall continue to be entitled to elect the
whole number of directors until the holders of Preferred Stock shall have
exercised their right to elect two directors voting as a class, after the
exercise of which right (x) the directors so elected by the holders of Preferred
Stock shall continue in office until their successors shall have been elected by
such holders or until the expiration of the default period, and (y) any vacancy
in the Board of Directors may be filled by vote of a majority of the remaining
directors theretofore elected by the holders of the class of stock which elected
the director whose office shall have become vacant.

     Immediately upon the expiration of a default period, (x) the right of the
holders of Preferred Stock as a class to elect directors shall cease, (y) the
term of any directors elected by the holders of Preferred Stock as a class shall
terminate, and (z) the number of directors shall be such number as may be
provided for in the certificate of incorporation or by-laws irrespective of any
increase made pursuant to the special voting rights of the holders of Preferred
Stock as described above. Any vacancies in the Board of Directors effected by
the provisions of clauses (y) and (z) in the preceding sentence may be filled by
a majority of the remaining directors.

                              INDENTURE SECURITIES
                              --------------------

8.   Analysis of indenture provisions. Insert at this point the analysis of
     indenture provisions required under section 305(a)(2) of the Trust
     Indenture Act of 1939 (the "1939 Act").

     The Debentures will be issued under an indenture to be dated as of
[________], 2004 (the "Indenture") and entered into by the Company and
[____________], as Trustee (the "Trustee"). The following analysis is not a
complete description of the Indenture provisions discussed and is qualified in
its entirety by reference to the terms of the Indenture, a form of which is
attached as Exhibit T3C hereto and incorporated by reference herein. The Company
has not entered into the Indenture as of the date of this filing, and the terms
of the Indenture are subject to change prior to its execution. Capitalized terms
used below but not defined have the meanings assigned to them in the Indenture.

     (a) Events of Default. The term "Event of Default" with respect to the
Debentures includes any of the following events:


                                       7




          (i)    default for 30 days in the payment of interest on the
                 Debentures (whether or not prohibited by the subordination
                 provisions of the Indenture);

          (ii)   default in payment of the principal of the Debentures when due
                 (whether or not prohibited by the subordination provisions of
                 the Indenture);

          (iii)  failure by the Company for 60 days after notice from the
                 Trustee or the holders of at least 25% of the outstanding
                 aggregate principal amount of the Debentures to comply with any
                 of its other agreements in the Indenture or the Debentures; or

          (iv)   certain events of bankruptcy or insolvency relating to the
                 Company as specified in the Indenture.

     The Indenture provides that the Trustee will, within 90 days after the
occurrence of a default that is continuing and known to the Trustee, give all
holders of Debentures notice of such default, provided, that, except in the case
of default in payment of principal of or interest on the Debentures, the Trustee
may withhold notice if it in good faith determines that the withholding of such
notice is in the interest of the holders of the Debentures.

     If any Event of Default occurs and is continuing, the Trustee or the
holders of at least 25% in principal amount of the Debentures then outstanding
may declare all the Debentures to be due and payable immediately. If the Event
of Default is an event of bankruptcy as described in (iv) above, all outstanding
Debentures will become due and payable without further action or notice.

     A declaration of acceleration may be rescinded by the holders of a majority
in aggregate principal amount of then outstanding Debentures if (a) the Company
has paid or deposited with the Trustee cash sufficient to pay all principal and
accrued interest on the Debentures and all fees and expenses of the Trustee, and
(b) all Events of Default, other than the non-payment of the principal and
interest on the Debentures that have become due solely by such declaration of
acceleration, have been cured or waived.

     (b) Authentication and Delivery of the Debentures; Application of Proceeds.

     The Debentures to be issued under the Indenture, in aggregate principal
amount of up to $320 million, may from time to time be executed on behalf of the
Company by its proper officers and delivered to the Trustee for authentication
and delivery in accordance with the Company's order and the Indenture. Each
Debenture shall be dated the date of its authentication, and no Debenture shall
be valid unless authenticated by manual signature of the Trustee, and such
signature shall be conclusive evidence that such Debenture has been duly
authenticated under the Indenture. The Debentures shall be in denominations of
$1,000 and integral multiples thereof.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Debentures. Unless otherwise provided in the appointment, an
authenticating agent may authenticate Debentures whenever the Trustee may do so.
Each reference in the Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent


                                       8




has the same rights as an agent to deal with the Company, any affiliate of the
Company, or any of their respective subsidiaries.

     There will be no proceeds (and therefore no application of such proceeds)
from the issuance of the Debentures because the Debentures will be issued as a
dividend to the holders of the Company's Common Stock.

     (c) Satisfaction and Discharge of the Indenture.

     The Company may terminate its obligations under the Indenture when (i) all
outstanding Debentures that have been authenticated and issued have been
delivered (other than destroyed, lost or stolen Debentures that have been
replaced or paid) to the Trustee for cancellation, (ii) the Company has paid all
sums payable by the Company under the Indenture and (iii) the Company has
delivered to the Trustee an officers' certificate and an opinion of counsel,
each stating that the foregoing conditions precedent have been complied with

          (e) Evidence of Compliance with Conditions and Covenants.

          So long as any of the Debentures are outstanding, the Indenture
requires that the Company will deliver to the Trustee:

     (i) within 90 days after the end of each fiscal year, a certificate signed
by two officers of the Company, one of whom must be the principal executive
officer, the principal financial officer or the principal accounting officer of
the Company, complying with Section 314(a)(4) of the Trust Indenture Act of 1939
and stating that a review of the activities of the Company during the preceding
fiscal year has been made under the supervision of the signing officers with a
view to determining whether the Company has kept, observed, performed and
fulfilled its obligations under the Indenture, and further stating, as to each
officer signing such certificate, whether or not the signer knows of any failure
by the Company to comply with any conditions or covenants in the Indenture
(determined without regard to any period of grace or requirement of notice) and,
if such signer does know of such a failure to comply, the certificate shall
describe such failure with particularity. The officers' certificate shall also
notify the Trustee should the relevant fiscal year end on any date other than
the current fiscal year end date; and

     (ii) promptly upon becoming aware of any Default, Event of Default or fact
which would prohibit the making of any payment to or by the Trustee in respect
of the Debentures, an officers' certificate specifying such Default, Event of
Default or fact and what action the Company is taking or proposes to take with
respect thereto. The Trustee shall not be deemed to have knowledge of any
Default, any Event of Default or any such fact unless one of its Trust Officers
receives notice thereof from the Company or any of the holders of the
Debentures.

9.   Other obligors. Give the name and complete mailing address of any person,
     other than the applicant, who is an obligor upon the indenture securities.

     None.
